Abstract

Many recent studies have focused on enhancing the efficiency of optical devices such as light-emitting diodes (LEDs). However, optical device efficiency decreases when generated light passes through the LED packaging material. Herein, we developed a technique to improve the effi ciency of LED packages and the external efficiency of the optical devices, which were packaged. Specifically, anti-reflection patterns consisting of moth-eye structures were used to prevent internal reflection from the surface of the LED package. These nanosized conical structures were fabricated with nano-imprint lithography, which is a next-generation lithography technology. Fine nanosized moth-eye patterns were formed on the surface of an LED package, increasing its efficiency by 3.27%.
